Hello!
The steps from the resolution recreate the link to /bin/which and there are not steps which may delete /bin/which.
As a solution for your case, I can suggest installing "which". As an example, for CentOS the command will be:
# yum install which
Following these instructions destroyed the `which` command completely.
Any instructions on how to fix a missing /bin/which?
